Hemi Le Fort III Fracture with Subdural and Subarachnoid Pneumocephalus with a Mild Mount Fuji Sign

ABSTRACT: Extensive fractures in the fixed facial skeleton combined with traumatic brain injury can cause functional and esthetic impairments, possibly threatening the patient's life. Male patient, 50-year-old, victim of physical aggression, presented with persistent headache and dizziness, fractures in the naso-orbito-ethmoidal, zygomatic-maxillary and right pterygoid process regions, among other minor patterns of facial fracture, with mobility to maxillary traction of the third midface unilaterally. Clinical-imaging findings revealed a Hemi Le Fort III fracture and subdural and subarachnoid pneumocephalus with a mild Mount Fuji Sign. The proposed treatment was facial osteosynthesis and conservative intravenous drug treatment of the pneumocephalus. The patient had a good recovery, with no postoperative motor or functional deficits. The correct management of the patient with facial trauma associated with craniotrauma offers benefits, restoring stability of facial architecture and preventing or correcting neurosurgical complications.

Surgical Treatment of Ameloblastoma: How Does It Impact the Oral Health-Related Quality of Life? A Systematic Review.

PURPOSE: This study aimed to analyze the impact of surgical treatment on the quality of life of patients diagnosed with ameloblastoma. METHODS: We searched PubMed, Science Direct, LILACS, EMBASE, and Web of Science, up to February 2021, with no time restriction. We considered only studies published in English that evaluated patients diagnosed with ameloblastoma who underwent conservative or radical surgical treatments using a quality of life (QOL) instrument. RESULTS: Of the 2155 studies identified, ten were included in our sample. Only studies that analyzed QOL of radical surgical treatment were included. No studies that analyzed QOL after conservative surgical treatment were found. Across all studies, 283 patients (122 females and 161 males; mean age: 28.13 years) were surgically treated for ameloblastoma. A total of 69 complications were reported, with the most frequent being infection in both the donor and recipient site (18 cases) and graft loss (8 cases). CONCLUSION: Surgical treatment of ameloblastoma was effective in providing reasonable health-related QOL, as most of the assessed dimensions were found to improve.

Efficacy of Photocoagulation of Vascular Malformations in the Oral Mucosa Using Nd: YAG Laser.

The purpose of this study was to analyze the effectiveness of Nd: YAG laser photocoagulation in the treatment of vascular malformations in the oral and perioral area; 93 patients (104 lesions) were evaluated in an Ambulatory of Oral Medicine (2006-2013). The sample consisted of 57 women (61%) and 36 men (39%), aged 8 to 85 years. The lesion size was smaller than 3 cm in most patients. The lesions were located on the lips, jugal mucosa, tongue, palate, gingiva, and retromolar trigone. All patients were treated on an outpatient basis using local anesthesia and Nd: YAG laser (Power Laser C ) with a wavelength of 1064 nm and a fiber optic diameter of 400 µm. After treatment no patients had complications, however, in patients of deep lesions, 2 or more irradiations were required to treat the lesions. Finally, the authors conclude that the clinical and aesthetic satisfactory results of the 93 patients treated with Nd: YAG laser suggest that this type of laser is effective and safe in the treatment of oral and perioral vascular malformations.

Diagnóstico à distância de lesões bucais com fotografias de smartphones / Remote diagnosis of oral lesions with smartphone photos

Objetivos: Avaliar o acerto diagnóstico entre a avaliação presencial de lesões bucais e a hipótese diagnóstica proposta à distância para uma amostra de imagens digitais obtidas por meio de um smartphone. Materiais e Métodos: O estudo teve desenho observacional transversal com amostra de conveniência. Os dados foram coletados no ambulatório de Estomatologia da Universidade Federal do Paraná, e obtidos a partir de exame físico oral, história da doença e registro fotográfico de lesões bucais realizado com um smartphone. Todos os pacientes que apresentaram lesões bucais visíveis à inspeção foram convidados a participar do estudo. A história clínica e as imagens dos participantes foram enviadas por e-mail para dois avaliadores, que foram solicitados a formular um mínimo de uma e máximo de duas hipóteses diagnósticas para cada caso. As hipóteses diagnósticas formuladas à distância foram comparadas com o padrão-ouro em cada caso clínico proposto, e medidas pelo coeficiente kappa. Resultados:O estudo avaliou uma amostra de 42 fotografias de lesões bucais obtidas de 23 pacientes. Em 91% e 87% dos casos, para os avaliadores 1 e 2, respectivamente, houve concordância do diagnóstico à distância comparado ao padrão-ouro. Os valores de concordância obtidos foram considerados ótimos de acordo com os valores de kappa (K = 0,864 - 0,909). Conclusão: O diagnóstico de lesões bucais por meio de imagens obtidas com um smartphone mostrou boa concordância e acerto diagnóstico comparável com aquele obtido presencialmente e pode ser sugerido como uma ferramenta auxiliar na referência de casos entre a atenção primária e a média complexidade em Estomatologia.

To evaluate the diagnostic accuracy between presential assessments of oral lesions and the diagnostic hypothesis proposed at distance with the use of a sample of photographs obtained with a smartphone.The study had a cross-sectional observational design with a convenience sample. The data were collected at the oral medicine ou patient clinic of Federal University of Paraná. They were obtained from clinical oral examination, a brief clinical history and photographic record of oral lesions taken with as martphone camera. The participants were all the patients with oral lesions visible to inspection. The clinical information and the photographs of were sent by email for two remote consultants, who weresolicited to formulate a maximum of two diagnostic hypotheses for each case. The diagnostic hypotheses formulated by the remote consultant were compared to the gold standard in each clinical caseand measured by the kappa coefficient. The sample was composed by 42 photographs of oral lesions obtained from 23 patients. In 91% and 87% of the cases, there was agreement from distant diagnosis when compared to the gold standard for consultants 1 and 2, respectively. The concordance obtained between the diagnostic hypotheses and the gold standard was considered “excellent” according to thevalues of kappa index (K = 0,864 - 0,909). The diagnosis of oral lesions through images obtained with as martphone showed good diagnostic accuracy and was comparable to that obtained in person. It canbe suggested as an auxiliary tool in refererring cases from primary to secondary care in oral medicine.

Caliber-Persistent Artery.

Caliber-persistent artery (CPLA) of the lip is a common vascular anomaly in which a main arterial branch extends to the surface of the mucous tissue with no reduction in its diameter. It usually manifests as pulsatile papule, is easily misdiagnosed, and is observed more frequently among older people, suggesting that its development may involve a degenerative process associated with aging; CPLA is also characterized by the loss of tone of the adjacent supporting connective tissue. Although the diagnosis is clinical, high-resolution Doppler ultrasound is a useful noninvasive tool for evaluating the lesion. This report describes the case of a 58-year-old male patient who complained of a lesion of the lower lip with bleeding and recurrent ulceration. The patient was successfully treated in our hospital after a diagnosis of CPLA and is currently undergoing a clinical outpatient follow-up with no complaints.

Clinicopathological aspects of 25 cases of sialolithiasis of minor salivary glands.

Sialolithiasis of minor salivary glands (SMSG) is rarely reported and presumably represents an underestimated disease. This study examined the clinicopathological aspects of 25 selected SMSG cases over an 11-year period at the Oral Pathology Department of the University of Sao Paulo, Brazil. SMSG was not a clinical diagnosis in 92% of the cases. Histologically, the sialoliths tended to be superficial and formed by concentric layers with variable degrees of mineralization. Chronic periductal and parenchymal inflammation were frequent, as well as squamous metaplasia of the affected duct. Ectasia, squamous and mucous metaplasia, mucous plug formation, and cellular debris were seen in adjacent ducts. Clinicians should be aware of SMSG, especially with regard to its higher incidence in the upper lip and buccal mucosa.

Câncer de boca baseado em evidências científicas / Oral cancer based on scientific evidences

Apesar dos inúmeros avanços no conhecimento científico do câncer de boca até o momento, muito ainda há para ser corretamente descoberto e compreendido. Convicções do passado foram substituídas por novas evidências científicas. O câncer de boca acomete cerca de 275.000 pessoas no mundo anualmente sendo mais de 14.100 casos no Brasil, em 90% dos casos é diagnosticado como carcinoma epidermoide. A taxa de mortalidade permanece praticamente a mesma de décadas passadas. Suas características clínicas são bastante conhecidas, mas apesar disso o número de pacientes diagnosticados tardiamente permanece alto. A biologia celular avançou muito, porém ainda carece de um marcador eficiente. A biópsia permanece como o padrão ouro do diagnóstico, apesar das pesquisas realizadas com outras técnicas. O tratamento odontológico de pacientes portadores de neoplasias malignas será cada vez mais comum nos consultórios e o Cirurgião-Dentista deverá estar preparado para diagnosticar e lidar com essas situações

Although the advances in the oral cancer knowledge, several issues have to be addressed for a better understood of this disease. Convictions of the past have been replaced by new scientific evidences. Oral cancer affects annually more than 275.000 people worldwide and more than 14.100 cases in Brazil, 90% of these are squamous cell carcinoma; the mortality rate remains the same for many decades. Their clinical characteristics are well known, but despite this, the number of patients with late diagnosis remains high. Cell biology had a great advance in the last years and a precise marker is still a dream. Biopsy remains the gold standard for diagnosis of oral cancer in spite of studies with other techniques. The dental treatment of oncologic patients will be more common and the dentist should be prepared to diagnose and manage these patients

Acupuncture for the prevention of radiation-induced xerostomia in patients with head and neck cancer.

The aim of this study was to evaluate the effectiveness of acupuncture in minimizing the severity of radiation-induced xerostomia in patients with head and neck cancer. A total of 24 consecutive patients receiving > 5000 cGy radiotherapy (RT) involving the major salivary glands bilaterally were assigned to either the preventive acupuncture group (PA, n = 12), treated with acupuncture before and during RT, or the control group (CT, n = 12), treated with RT and not receiving acupuncture. After RT completion, clinical response was assessed in all patients by syalometry, measuring the resting (RSFR) and stimulated (SSFR) salivary flow rates, and by the visual analogue scale (VAS) regarding dry mouth-related symptoms. Statistical analyses were performed with repeated-measures using a mixed-effect modeling procedure and analysis of variance. An alpha level of 0.05 was accepted for statistical significance. Although all patients exhibited some degree of impairment in salivary gland functioning after RT, significant differences were found between the groups. Patients in the PA group showed improved salivary flow rates (RSFR, SSFR; p < 0.001) and decreased xerostomia-related symptoms (VAS, p < 0.05) compared with patients in the CT group. Although PA treatment did not prevent the oral sequelae of RT completely, it significantly minimized the severity of radiation-induced xerostomia. The results suggest that acupuncture focused in a preventive approach can be a useful therapy in the management of patients with head and neck cancer undergoing RT.

Fine needle aspiration biopsy in the oral cavity and head and neck region.

The objective of the current study was to evaluate the sensitivity, specificity and accuracy of fine needle aspiration biopsy (FNAB) of submucous nodules from the oral cavity and head and neck region as an auxiliary diagnostic tool. Fifty patients with nodule lesions in the oral cavity and the head and neck region were selected. All of them were submitted to FNAB and to either incisional or excisional biopsy. The diagnoses from the FNABs were compared with the biopsy diagnosis as the gold standard. All the cases of FNAB were analyzed by a single oral pathologist prior to the biopsy diagnosis. The results showed that the sensitivity of FNAB was 75%, its specificity was 96% and its accuracy was 58.8%. The false positive and false negative rates were 6.7% and 13.3%, respectively. The positive predictive value was 86% and the negative predictive value was 93%. The inconclusive rate was 16/50. FNAB displayed a high success rate for identifying both malignant and benign lesions, but a low accuracy for making a final diagnosis.

Keratoacanthoma of the lower lip: still a matter of diagnosis / Ceratoacancoma do lábio inferior: ainda um problema de diagnóstico

Introduction: Keratoacanthoma is a lesion that may mimic squamous cells carcinoma clinically and histologically and the distinction between both lesions has been a matter of discussion. Typical lesions consist of a firm dome-shaped nodule, 1 to 2 centimeters in diameter, with a horn-filled crater in its center. Objectives: To present it was selected an atypical case of a 43-year-old woman who had a solitary keratoacanthoma (KA) of the lower lip with a history of two years of evolution and mistreatment and to discuss the difficulties of the diagnosis process. Conclusion: Because of the rarity of the lesion and its similarity with squamous cells carcinoma the general dentist must explain to the patient that the clinical aspects are not conclusive of the diagnosis and a correct acquisition of the surgical specimen is crucial to an accurate histopathological interpretation and conclusive diagnosis.

Introdução: O ceratoacantoma é uma lesão que pode mimetizar clínica e histologicamente o carcinoma espinocelular, sendo discutível a distinção entre as duas lesões. As lesões típicas consistem em um nódulo firme, em forma de cúpula, com 1 a 2 centímetros de diâmetro e uma cratera central preenchida com queratina. Objetivo: Apresentar um caso atípico de uma mulher de 43 anos que apresentava uma lesão solitária de queratoacantoma no lábio inferior, com uma história de dois anos de evolução e erros de tratamento e discutir a dificuldade no processo de diagnóstico. Conclusão: Devido à raridade da lesão e sua semelhança com o carcinoma, o clínico geral deve explicar ao paciente que os aspectos clínicos não são conclusivos do diagnóstico e que a aquisição correta do espécime cirúrgico são cruciais para a análise histopatológica correta e para o diagnóstico conclusivo.

Reviewed evidence about the safety of the daily use of alcohol-based mouthrinses

Current scientific knowledge provides clear evidence that alcohol-based mouthwashes can be beneficial in a daily oral health routine, including dental hygiene and plaque control. Several issues are worth discussing, in spite of the wealth of supporting evidence. Despite some undesirable effects to some people, like burning sensation, and some contraindications, like the use by infants, alcohol addicts and patients with mucosal injuries, there is no reason to avoid the use of alcohol-containing mouthwashes as long as they are used following proper guidance by dental professionals and the manufacturers' instructions. The alleged correlation between oral cancer and alcohol-based mouthrinses presents so little, weak, inconsistent and even contradictory evidence in the literature that any kind of risk warning to patients would be uncalled for. Antimicrobial mouthrinses are safe and effective in reducing plaque and gingivitis, and should be part of a comprehensive oral health care regimen that includes brushing, flossing and rinsing to prevent or minimize periodontal disease.

Manifestações clínicas intrabucais da doença de Crohn – Relato de caso clínico / Oral manifestation in Crohn’s Disease − Case report

A doença de Crohn é uma doença inflamatória granulomatosa, de etiologia desconhecida, mas de natureza imunológica relacionada a uma suscetibilidade genética. A doença foi descrita pela primeira vez por Crohn e colaboradores em 1932, usando o termo inflamação regional do íleo. Atualmente está claro, que qualquer nível do trato gastrintestinal pode ser acometido. A doença afeta pacientes jovens e pode se apresentar da forma aguda ou crônica podendo ocorrer diversas manifestações sistêmicas, inclusive na cavidade bucal. O tratamento médico varia em função do quadro clínico e muitas vezes se baseia apenas no controle dos sintomas. A prevalência na cavidade bucal varia conforme a faixa etária atinge ambos os sexos e é mais prevalente em leucodermas. Essa doença apresenta um polimorfismo de lesões bucais, muitas vezes de maneira inespecífica. Em aproximadamente 30por cento dos casos as lesões bucais precedem as manifestações sistêmicas O relato de caso explorou a literatura atual e enfatizou os aspectos clínicos odontológicos, os diagnósticos diferenciais e o papel do cirurgião-dentista no diagnóstico precoce dessa doença.

O papel da tomografia computadorizada no diagnóstico, planejamento cirúrgico e acompanhamento das displasias fibrosas / The status of computed tomography in the diagnosis, surgical planning, and evaluation of fibrous displasias

As lesões-fibro ósseas se caracterizam pela substituição da estrutura óssea presente por tecido fibroso. As características clínicas, radiográficas e histopatológicas são importantes para o diagnóstico final da lesão. Os autores discutem quais as indicações da tomografia computadorizada (TC) no diagnóstico, tratamento e acompanhamento das displasias fibrosas, realçando as características radiográficas observadas na TC, ilustrando um estudo de caso clínico.

Fibrous-osseous lesions are characterized of the replacement of osseous structures by the current fibrous tissues. The clinical, radiographic, and histopathological characteristics are important for the final diagnosis of the lesion. The authors discuss which indications of computed tomography (TC) for the diagnosis, treatament and evaluation of fibrous dysplasias, emphazising the radiographic characteristics seen in CT, and showing a case report.

Criocirurgia – Uma alternativa no tratamento de lesões benignas da mucosa bucal / Cryosurgery – an alternative treatment in cases of benign oral lesions

Uma grande variedade de doenças bucais é encontrada em nossa prática clínica diária. A criocirurgia é um método alternativo para o tratamento de algumas lesões benignas e apresenta vantagens sobre outros. É uma modalidade terapêutica muito utilizada em outros países desde a década de setenta, porém pouco utilizada em nosso meio. Os autores apresentam uma breve revisão da literatura e seus resultados na utilização da técnica em 37 lesões bucais. A criocirurgia é bem aceita pelo paciente e mostrou-se bastante simples, de fácil execução, relativamente barata e eficiente. Foram obtidos resultados positivos no tratamento de hiperplasia fibrosa inflamatória, papiloma, mucocele e particularmente em hemangiomas (más-formações vasculares). No tratamento da leucoplasia os resultados são imprevisíveis. A criocirurgia tem apresentado poucos efeitos adversos. Os resultados podem variar de acordo com o tipo de lesão.

Clinical evaluation of the topical use of propolis in recurrent minor aphthous ulceration

Nosso objetivo foi avaliar os efeitos terapêuticos da própolis em ulcerações aftosas recorrente (UAR) do tipo minor em relação ao número de lesões, duração e freqüência das lesões. Setenta pacientes com UAR compuseram o grupo estudado que foi examinado conforme critério de inclusão pré-estabelecido. Quarenta pacientes que apresentavam UAR (idade média de 38,5 anos; 25 mulheres e 15 homens) foram selecionados e medicados durante os episódios recorrentes de UAR utilizando-se uma solução de própolis a 5% tendo o propilenoglicol como veículo. Os pacientes foram orientados a aplicar topicamente a solução três vezes ao dia, a partir dos primeiros sinais clínicos de UAR pelo período de um ano. Foi observada uma redução estatisticamente significante no número, freqüência e duração das lesões (p≤ 0,01). A solução de própolis utilizada como terapia das UAR nesse estudo não apresentou efeitos adversos e se mostrou benéfica no tratamento das ulcerações aftosas recorrentes.
